TE Connectivity 1-2029027-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-2029027-6 is a 16-position rectangular connector plug housing from the VAL-U-LOK series, designed for crimp contact termination with a 0.165" (4.20mm) pitch configuration. This connector features a black polyamide housing, free-hanging in-line mounting, and locking ramp fastening. The part is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain electrical and mechanical compatibility for ongoing applications and new designs.

Substitute Part Grouping Explanation

Substitution of the 1-2029027-6 is determined by strict equivalence across the following critical parameters: connector type (plug), contact type (male pin), number of positions (16), pitch (0.165"/4.20mm), number of rows (2), row spacing (0.165"/4.20mm), mounting type (free hanging in-line), contact termination (crimp), and fastening type (locking ramp). All substitute parts must maintain these electrical and mechanical specifications to ensure form, fit, and function compatibility.

Variations in color (black, natural, white) and insulation material composition (PA versus PA66) do not affect substitution eligibility when all core parameters remain identical. Operating temperature range, RoHS compliance status, and product status (active versus obsolete) are secondary considerations that inform selection strategy but do not preclude substitution based on parametric equivalence.

Engineering Selection Recommendations

Primary Substitutes (TE Connectivity VAL-U-LOK Series)

The parts 1-1586000-6, 1-1969604-6, and 1-1969612-6 are parametric equivalents within the VAL-U-LOK series. All three are active products with full RoHS compliance. The 1-1586000-6 and 1-1969604-6 maintain identical insulation material composition (PA/Nylon) to the original 1-2029027-6, differing only in color (natural versus black). The 1-1969612-6 uses PA66 (Nylon 6/6) insulation material and carries ROHS3 compliance, providing enhanced material specification for applications requiring higher performance standards.

Secondary Substitute (TE Connectivity AMP-DUAC Series)

The 1-794594-6 is an active product from the AMP-DUAC series with extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 105°C). This part is suitable for applications requiring lower temperature operation. The white color and identical electrical/mechanical parameters maintain full compatibility.

Alternative Manufacturer Substitute (CNC Tech)

The 4282-3-16-D from CNC Tech provides a cross-manufacturer equivalent with PA66 insulation material and ROHS3 compliance. This part is suitable for applications where multi-source qualification is required or where CNC Tech components are preferred within the supply chain.

Selection Criteria

For direct replacement of the obsolete 1-2029027-6 in existing designs, 1-1586000-6 or 1-1969604-6 are recommended due to identical material composition and series continuity. For new designs or applications requiring enhanced material properties, 1-1969612-6 or 4282-3-16-D are appropriate selections. Color selection (natural, white) should be determined by application requirements and assembly specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1-1586000-6 directly replace the obsolete 1-2029027-6?

A: Yes. The 1-1586000-6 is a parametric equivalent with identical electrical and mechanical specifications. The only difference is housing color (natural versus black). Both parts use the same insulation material (PA/Nylon), pitch (0.165"/4.20mm), 16-position configuration, and locking ramp fastening. The part is active and in stock.

Q: What is the difference between 1-1969604-6 and 1-1969612-6?

A: Both parts are parametric equivalents with identical connector specifications. The primary difference is insulation material: 1-1969604-6 uses PA (Polyamide) while 1-1969612-6 uses PA66 (Nylon 6/6). The 1-1969612-6 carries ROHS3 compliance versus standard RoHS compliance. Material selection depends on application requirements for thermal or mechanical performance.

Q: Is the 1-794594-6 compatible with the original 1-2029027-6?

A: Yes, the 1-794594-6 is mechanically and electrically compatible. It maintains all critical parameters: 16 positions, 0.165" pitch, 2 rows, crimp termination, and locking ramp fastening. The 1-794594-6 belongs to the AMP-DUAC series and features an extended operating temperature range (-55°C ~ 105°C). Housing color is white instead of black.

Q: Can I use the CNC Tech 4282-3-16-D as a substitute?

A: Yes. The 4282-3-16-D meets all parametric requirements for substitution: 16 positions, 0.165" pitch, 2-row configuration, crimp termination, and locking ramp fastening. This part is from an alternative manufacturer and uses PA66 insulation material with ROHS3 compliance. It is suitable for applications requiring multi-source qualification.

Q: Does housing color affect electrical performance?

A: No. Housing color (black, natural, white) is a cosmetic specification that does not affect electrical or mechanical performance. Color selection is determined by application requirements, assembly specifications, or visual identification needs.

Q: What does "Contacts Not Included" mean?

A: All listed parts are connector housings only. Crimp contacts must be sourced separately and are not included with the housing. Contact selection must match the 0.165" (4.20mm) pitch specification and crimp termination method.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry either RoHS or ROHS3 compliance certification. The original 1-2029027-6 is RoHS Compliant. Substitutes 1-1586000-6, 1-1969604-6, and 1-794594-6 are RoHS Compliant. Substitutes 1-1969612-6 and 4282-3-16-D are ROHS3 Compliant, which represents an enhanced compliance standard.

Q: What is the difference between VAL-U-LOK and AMP-DUAC series?

A: Both are TE Connectivity connector series with identical parametric specifications for this 16-position configuration. The VAL-U-LOK series includes parts 1-1586000-6, 1-1969604-6, and 1-1969612-6. The AMP-DUAC series includes part 1-794594-6. Series designation reflects product line organization but does not affect mechanical or electrical compatibility.

Q: Can I mix and match housings from different manufacturers?

A: Yes, provided all parametric specifications remain identical. The TE Connectivity parts (1-2029027-6, 1-1586000-6, 1-1969604-6, 1-1969612-6, 1-794594-6) and the CNC Tech part (4282-3-16-D) are all parametrically equivalent and can be used interchangeably in applications where the 16-position, 0.165" pitch, crimp-terminated plug housing is required.
